This is a set of two optional RPM In-Line Steering Blocks, and are intended for use with the HPI Blitz and Firestorm short course trucks. Just a short time ago, RPM engineers designed new rear bearing carriers for the HPI Blitz and Firestorm lines of vehicles that incorporated 5x11mm bearings, improving durability and performance significantly. That same bearing size is now available for the front end of those same vehicles! RPM In-Line Steering Blocks incorporate a 5x11mm bearing, which has nearly twice the dynamic load rating as the stock 5x10mm bearing. That’s nearly twice the muscle to make a strong truck nearly bulletproof! RPM In-Line Steering Blocks incorporate all stock geometry for a perfect fit and are molded from our ultra durable blend of nylons for a significant improvement in durability and strength as well.

NOTE: 5x11x4mm bearings are not included with these kits (4 bearings are needed for each kit). RPM In-Line Steering Blocks are “stock” replacement parts for the HPI Firestorm Line of vehicles while they are the “optional” replacement steering blocks available for the HPI Blitz line of trucks.

This product was added to our catalog on June 7, 2010.

Have not had any problem with the screws backing out, but these things are VERY strong. i was brand new to this, and ran into door frames at almost full speed several times with the factory original part, and broke it. Put these on, still ran into the door frames at nearly full speed...no problems! Very strong.

The RPM arms are good because they use a bigger 5X11 bearing and the plastic seems stronger than the stock arms but the problem I had was that the screws backed out of the arms after a few runs. That didn't happen with the stock arms so if you run these, you need to put a drop of superglue on the threads to keep them from backing out. After glueing, the screw seem to be staying in place and they should be more durable than stock as long as the screws stay in place.
